Preparation

Beginning with the vanilla cake, whisk together the flour, sugar, baking powder and soda, and salt in a large bowl. Once the dry goods are well-distributed, turn your attention to the wet ingredients. In a separate bowl, combine the non-dairy milk of your choice with the lemon juice, allowing it to sit for about 5 minutes to curdle slightly. Add in the oil and vanilla, stir thoroughly, and introduce this liquid mixture to the bowl of dry ingredients.

Mix gently with a wide spatula, stirring just enough to bring the batter together with few remaining lumps. Transfer into your prepared loaf pan, smooth out the top, and slide it into the center of your oven. Bake for 50 – 55 minutes, until lightly golden brown all over and a toothpick inserted into the center comes out cleanly. Let cool completely and chill for at least 1 hour before proceeding.

Once your cake is nice and cold all the way through, use a very sharp serrated knife to slice it into 1-inch thick slabs. Take a large heart-shaped cookie cutter that fits within the confines of the slices and punch out your heart shapes; cover with plastic wrap to prevent them from drying out and set aside.

Moving on to the Wild Blueberry batter, toss the berries into your blender or food processor, and thoroughly puree. Slowly drizzle in the water, lemon juice, oil, and vanilla to incorporate. Add in the sugar into the machine last, and continue blending until completely smooth, with just a few visible seeds remaining.

In a separate bowl, mix the flour and baking powder, soda, and salt. Just as before, pour the liquid mixture into the bowl of dry goods, stirring to combine with as few strokes as possible.

Pour a thin layer of the batter into the prepared loaf pan, spreading it out smoothly so that it evenly reaches about ½ – ¾ of a centimeter all the way across the bottom. Retrieve your heart-shaped vanilla cake cut-outs, and line them up in a row along the center. Naturally, they’ll fit if you can arrange them in the same order as they were cut, but it will work just as beautifully if they’ve gotten mixed up too. Pour the remainder of the blue batter around the sides and over the tops of the hearts, being careful to fill up any crevasses. Tap the pan firmly but gently on the counter to release any air bubbles that may disrupt the pattern. It’s likely that you’ll end up with some extra batter that won’t fit into the pan; bake it off separately as cupcakes or mini-loaves to enjoy later!

Carefully slide the loaf pan into the oven and bake for 30 – 45 minutes, until a toothpick inserted into one of the blue sides pulls out cleanly. Don’t test for doneness in the center; of course the vanilla cake will be done, since it was already well-baked to begin with!
